@Avatar6: Good question, see for instance its usage on marathon (Q40244). 42.195 km is not the dimension of the object “marathon”. It is the distance between the start and finish line of a marathon. And while the English alias “distance” might perhaps allow such a statement, this is not the case for the German aliases which only cover physical dimensions of an object. What to do? —MisterSynergy (talk) 08:04, 5 August 2016 (UTC)

The distinction between dimension and distance was even made during P2043’s proposal, but somehow it got lost. Shall I just go to property proposal to ask for a distance property? —MisterSynergy (talk) 05:29, 9 August 2016 (UTC)
